Comparative Study On Reinforced Concrete Pile Wall -and Soldier Pile Wall With Timber Lagging (shoring)

In the recent year the construction of high rise buildings are significantly increasing in ourrncountry. Those buildings require large parking area, stores and other facilities that can only bernfulfilled by constructing basements. For the construction of basements and underground passesrnhave created need to go deep excavations into ground. Deep excavations are supported byrnshoring systems or pile walls. The project seeks to find out the better option betweenrnreinforced concrete pile wall and soldier pile wall with timber lagging in cost savings andrnfeasibility of internal stabilized which have advantage like material availability, constructionrncost effectiveness, durability, easy construction and corrosion resistance and so on, for ourrncountry context. rnTo achieve this objectives design reinforced concrete pile wall and soldier pile wall withrntimber lagging at different pile spacing (0.6m,0.9m ,1.2m,1.5m and 1.8m)and first anchor level rn(3.5m,3.7m,4.0m,4.5m and 5.0m) using deepXcav software, excel spread sheet and handrncalculation done and based on the outputs form these analysis have been done cost estimationrn(bill of quantity) preparation for the purpose of cost comparison. rnFinally, the comparison of the two shoring system is carried out based on safe design and therncost efficient. The cost analysis and the optimum design disclose that the cost of solider pilernhigher than reinforced concrete pile wall.
